JONATHAN GUILER, OF CHICOPEE, MASSACI-IUSl'lTS.`

MACHINE FOR-MAKING CLASES. i

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, JONATHAN CUTLER, of the town of Chicopee, county ofHampden, and State of Massachusetts, have invented new and usefulimprovements in the mode of constructing machines for cutting out andforming clasps for the use ofparasols and other articles; and I doherebydeclare that the following is a correct description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon.

The nature of my invention consists in the general arrangement andapplication of a series of cams, slides, and other attachments, to forma partially automatic machine to make metal clasps.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

Figure l a general ground plan. Fig. 2 plan of reciprocating ring,slides &c. Fig. 3 a portion of the ring showing the inner cam recesses.Fig. 4 a vertical section longitudinally from X to X. Fig. 5 view of thedisk of the cam F. Fig. 6 view of the underside of die, punches, centerpin, &c.

Fig. 7 a clasp before being formed. Fig. 8 a ditto when completed.

The general construction of my machine is nearly similar to otherstamping and punching machines, so far as to the use of cams, levers,&c.

My improvements are in the application of a series of sliding formers,A, and other parts, actuated by the reciprocating ring C, and incombination with the rotating cams D, E, F, for cutting out, punching,and shaping thin metal for clasps. The slides A, are actuated by thevibratory movement of the external ring C. The beveled recesses L, inthe inside of the same press against the ends of the said slide formersA causing them to slide inwardly,V in concert, to the center, their endsbeing properly formed to shape the clasps as desired, after beingcut andpunched by the operation of the die and stock S. The vibratory movementof the ring C is caused by the lever I, and the pin M, working ortraveling in the groove N 0f the rotary cam D.

The lever Gr Figs. 1-4 vibrates vertically on the pin O, and has a pinP, on the other end to travel in the groove of the disk of the cam EFig. 4 the movement of this lever 26,419, dated December 13, 1859.

Gr, raises and falls the vertical stamp stock S, to operate on themetal, in unison with` y tllue slides, and other apparatus to form the casp. The spring leverf1 H, `Figs 1-5, is the feed motion, to pass in themetal to the dies, and is actuated `by the cam F, and pinU.` y The metalis placed between the plates T, for operation, the spring lever H beingadjustable, and attached at the inner end, and the cam .F revolving, itscam form lifts up Y the upper plate T, to relieve the metal` and allowit to pass in to, `and under the dies, by the vibratory motion of thelever H, the g plate then closes down on the metal to hold y it whilebeing stamped, the whole operating in unison with the alternate risingand falling of the die andpunches.

The center spring pin W, p F ig. 4, is placed in the center of the diestock S, this pin is to press down the' blank, (after being cut,)through the die plate, on to the former f bed Y, ready for the slideformers to operate on, and holds it down on the bed plate Y, while theslide formers A come forward y and complete the shape of the clasp.

Then all the movements separate `and throw open the hole in the bottom,and the finished clasp falls through the spring vibrating lever B, Fig.2 is to pass forward l and backward the pin Z, to form the back part ofthe clasp. The cam slots in the' plates on the upper part of thecircular bottom, X, Fig. 1, are to givethe` backward movement to theslide formers A. What I claim as my `invention and desire i to secure byLetters Patent isf i l. The sliding formers A, and thevibrating lever B,in combination with the 'die i and punches in the mannerhereindescribed. 2. The reciprocating ring C, to actuate the slideformers A, in combination with the revolving cam D, and lever arm I andpin M. y 3. The center springpin IV, to press the 1001 blank downthrough the die plate, onto the n forming bed, Y, inthe mannerdescribed.` 4. I claim the whole arrangement incom`` f y binat-ion, asan organized automatic machine 1i in the manner and for the purposespecified, l substantially as set forth. y `JONATHAN GUTLER.
